Morning
I wake before Lena.
For a few minutes I stay in bed looking at the ceiling.
Last night I was certain when I said it.
Today it sounds bigger.
To hold control from beginning to end.
Not for a few minutes. Not until the game shifts and she takes the reins back. For hours.
I get up and make coffee.
The computer is closed on the living-room table. I don’t open it.
I don’t want numbers today.
Or comments.
Lena appears in the kitchen a little later.
We talk about the coffee running out, the washing machine that needs emptying, whether Anna remembered sunscreen.
But what I proposed last night is there between us.
“Did you mean it last night, or did you say it because you were still inside the scene?”
I look at her.
I expected this.
“I meant that I wanted to hold control from beginning to end. Saying it afterward doesn’t make it less true.”
She looks at me over the rim of her cup.
“You know I don’t mean just control. I mean everything that comes with it.”
I take a sip.
I know.
Or at least I’m trying to understand exactly what it means.
“I know. And I meant it.”
“From the first command until the collar comes off?”
“From beginning to end, without switching roles when it gets difficult.”
“It could be several hours. I don’t want you treating it like a performance that has to be completed.”
“I don’t want to prove I can do it. I want to see if we can do it properly.”
That’s true.
Last night there was something else in me too.
A need to see what it’s like when the framework isn’t hers.
Today that seems a little childish.
If she genuinely gives me control, I won’t have anyone else to blame for how the evening unfolds.
It will be my responsibility.
“I’m trying to figure out whether you know what you agreed to or whether you’re discovering it now with me.”
“I’m discovering it now. Do you know more?”
She sets her cup down.
“Not completely. I only know I want to try it with you.”
The answer hits me harder than I show.
With you.
“Good. Then we’re two people who know the rules and not the outcome.”
I slowly stir the spoon around my cup even though the sugar has dissolved.
I don’t know whether Lena notices.
It doesn’t matter.
We bring out a notebook and pen.
I write down the start time.
Eight.
Beside it, the end time.
Eleven at the latest.
“Yellow?”
“You lower the intensity or we change something.”
“Red?”
“We stop immediately.”
I write the words down.
“If I’m not sure, I’ll ask for your color.”
“And if I need to speak, I’ll speak. Even if you’ve told me to be quiet.”
“Agreed.”
We go over what isn’t allowed, what can be tried, and what she wants left out of the evening.
I write everything down.
I don’t want to rely on the fact that I’ve known her for twenty years.
Maybe that’s one of our problems.
We think that because we’ve known each other for years, we always know what the other person wants now.
“And when it ends?” she asks.
“Then it ends.”
“That simple?”
“You take off the collar and I’m Manos again.”
“The one who forgets his glasses?”
“That one.”
She writes something at the bottom of the page.
“Good to remember.”
I lean over.
“What did you write?”
“‘Remember his glasses.’”
“Very serious preparation.”
Her phone vibrates.
Anna.
“We’re taking a little boat trip today. Don’t worry if I don’t have a signal.”
Lena replies:
“Keep your phones charged and text when you get back.”
I read over her shoulder.
“You restrained yourself. I expected at least three safety instructions and a weather forecast.”
“I wrote them all and deleted them. The life jacket almost survived.”
“That’s progress worth entering into the family archives.”
She laughs.
I laugh with her.
It’s a small thing.
Maybe so small I wouldn’t have noticed it a week ago.
Lena writes every instruction she wants to give Anna.
Then decides on her own that none of them are necessary.
I don’t know why I hold on to that.
But I do.
Midday
We empty the washing machine, walk to the supermarket, and come home with more than was on the list.
In the paper-goods aisle Lena puts two different packs of paper towels in the cart.
“Choose.”
I look at her.
“Aren’t you supposed to stop making decisions tonight?”
“Starting at eight. Until then, choose the paper towels.”
I pick up both packages as if I’ve been assigned an important financial decision.
“I can feel the power already.”
I compare prices and sheet counts.
Lena watches me.
I don’t give her the satisfaction of deciding quickly.
If she’s going to give me authority, she can wait.
We eat pasta in the kitchen.
Neither of us talks about the evening.
Lena checks the time.
Then again.
And a third time.
“The clock works,” I say without looking up from my plate.
“I’m checking.”
“Three times in seven minutes?”
“It’s a sensitive mechanism.”
I smile.
She knows I know.
A little after six, Anna texts to say they’re back and everything is fine.
Lena replies and puts her phone on the charger.
I look at the phone.
“Should we leave the phone close enough to hear it?”
“For Anna?”
“Yes. I don’t want the role to make us forget she might need her parents.”
Lena looks at me for a moment.
“In the next room, volume up. Close enough to hear, not inside the scene.”
“Agreed. That way neither of us has to wonder whether we missed a call.”
I don’t want the role to swallow everything else.
Not her.
Not me.
In a few hours I need to be able to close the door, take the collar off her neck, and become the man who’ll answer the phone if his daughter calls.
The thought calms me.
Preparation
A little before seven I go into the bedroom alone and close the door.
I open the drawers.
I take out everything we agreed on.
Blindfold.
Soft cuffs.
Vibrator.
Two soft clamps.
The small flogger.
I line them up on the low table.
Beside them I put two glasses and the bottle of whiskey.
I leave a clean towel and blanket on the chair.
The collar comes out last.
Black, simple, soft synthetic leather. A metal buckle at the back and a small ring in front. It isn’t heavy or theatrical.
I leave it in the center.
I close the curtains. I switch on the two low lamps so the center of the room stays brighter than the corners.
I look at the room.
I don’t want anything to look improvised.
Or more theatrical than it needs to be.
I open the closet and take out my most expensive suit. Dark jacket, white shirt. I leave the collar open, no tie.
For a few seconds I look at myself in the mirror and feel ridiculous.
Then I think that if I laugh at this before we start, I’ll be doing exactly what I asked her not to do to me last night.
I take it seriously.
That’s what I asked for.
When I come out of the room, Lena is in the living room with a book open.
I don’t explain anything.
“At eight.”
She goes to the bathroom.
I return to the bedroom.
I button my jacket.
I look once more at the objects.
Last night I wanted to know what it would be like if the framework were mine.
Now it is.
And the first thing I feel isn’t power.
It’s responsibility.
The Ritual
At exactly eight, the door opens.
Lena stands in the doorway wearing the thin black robe.
She stops when she sees me.
For a moment I have the absurd urge to smile and break the tension.
I don’t.
I look at her.
She’s the woman I went shopping for paper towels with a few hours ago.
And she isn’t.
Her gaze goes to the table.
Then to the collar.
Back to me.
I begin exactly as we agreed.
“Are you choosing freely to participate?”
“Yes.”
“Do you want to continue?”
I keep my eyes on hers.
“Yes, Master.”
The word hits me harder than I expected.
I don’t let it show.
I pick up the collar.
I stand behind her and gather her hair with one hand.
The material feels cold against her neck.
I close the buckle and slide two fingers between the collar and her skin.
I check it again.
I take a slow breath before moving my hands away.
It’s strange.
For years I told myself Lena left no room.
Now she’s standing in front of me and giving me more room than I ever clearly asked her for.
I don’t feel vindicated.
I feel as if I need to be very careful with what I do with it.
I say nothing.
The First Hour
I stand across from her.
“In front of me.”
She takes two steps.
“Closer.”
She moves closer.
“Hands behind your back.”
She puts them behind her waist and brings her palms together.
“Look at me.”
She raises her eyes.
“How will you answer me?”
“Yes, Master.”
“If you don’t understand a command?”
“I’ll ask you to repeat it, Master.”
“If you want to stand, touch me, or change position?”
“I’ll ask permission.”
I leave her waiting.
I try not to rush because I’m nervous.
My suit.
Her robe.
The collar.
Everything makes the difference between us look larger.
“Open the robe.”
She unties the belt.
The fabric opens.
I let my gaze travel down, then bring it back to her face.
“Take it off.”
The robe falls to the floor.
“Pick it up.”
She bends, picks it up, and waits.
“Leave it on the chair.”
She places it on the blanket and returns to me.
I didn’t tell her to come back.
For a fraction of a second I consider letting it go.
I don’t.
If we’re going to do this, we’ll do it the way we agreed.
I look at her.
She understands.
“Did I tell you to come back?”
She stops.
“No, Master.”
“Then?”
“I should have waited.”
“Go back to the chair.”
She returns.
She stands there naked.
I see the awkwardness on her face.
I don’t intervene.
I wait until she stops trying to guess what I want.
“Now you can come here.”
She approaches.
“Kneel.”
She lowers herself to her knees.
The image affects me immediately.
More than I’d like to admit.
“Look at me.”
She lifts her head.
I slide one finger under the collar and pull it slightly toward me.
Her hand moves toward my leg.
“Don’t touch.”
She stops before making contact.
“Ask permission.”
“May I touch you, Master?”
I leave her there for a few seconds.
“You may.”
She places her fingers low on my pants.
They move up to my knee and a little higher.
My muscles tighten under the fabric.
“Stop.”
She pulls her hand away.
I pick up the blindfold.
Before putting it on, I stop.
“Do you want to continue?”
“Yes, Master.”
I fasten it.
Her gaze disappears.
And with it disappears one of the easiest ways I have to check how she’s doing.
Now I have to listen to her body.
Her breathing.
Her voice.
I rest my hand on her shoulder, slide it down her back to her waist, and grip.
She stays still.
“Stand.”
She rises slowly.
I fasten the soft cuffs around her wrists and raise her hands above her head.
I watch her test the movement slightly.
There’s enough room.
She relaxes.
